Optimal PV Layout Design and Infrastructure
DLR Group provided racking design and electrical pathway design, and coordination services for the four-megawatt rooftop solar system through collaboration with Duke Energy Sustainable Solutions and in collaboration with the overall building design team. Through advanced parametric modeling and clash detection, a well-crafted rooftop solar design was born. The design considered environmental conditions including thermal expansion, seamless integration with other complex building systems, and ease of maintenance. The result is an optimal PV layout that yields the highest possible coverage of surface area on the complex roof geometry. Seismic bracing and support design considerations for PV electrical conduit infrastructure were also key. Routing intricacies through a substantial number of tightly fitting conduits up cruciform columns was like threading a needle. This involved going through the building structure, weaving to pass through the façade, above the roof, and below the modules.
